I PROTECTOR FOR WIRES, RODS, &c., IN RAILWAY SIGNAIJNG AND SWITCHING S YSTEMS.

SPECIFICATION forming part of Letters Patent No. 593,869, dated November 16, 1897.

Application filed April 6, 1897 Serial No. 630,980. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN WRIGLEY, a citi-.

zen of the United States, residing in Elmira, Chemung county,a'nd State of New York-,have invented certain new and useful Improvements in Protectors for Wires, Rods, &c., in Railway Signaling and Switching Systems; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my present invention is to provide simple and effective means for protecting wires, chains, rods, pipes, pulleys, &c., suchas are used in railway systems in connection with semaphores, railway-gates, switches, and the like, to thus render such systems more durable and prevent the same from getting out of order through the effect of water,.frost, mud, 85c.

The invention consists in the improved means for protecting pipes, wires, rods, pulleys, &c., of the character above described, and in the combination and arrangement of the various parts thereof, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in. which like letters of reference indicate corresponding parts in each of the several views, Figure 1 is a front elevation of a semaphore having its operating wires and pulleys provided with my improvements; Fig. 2, a side elevation of Fig. 1 and also illustrating the underground wires leadingto the operating-tower, which wires are also provided with my improved protective means, Fig. 3, an enlarged detail view of the protector proper, certain portions being broken away and others shown in section to better illustrate the nature of my said invention; Fig. 4, an enlarged sectional view on the line a: 00 of Fig. 3; Fig. 5, an enlarged detail view of a certain cap for connecting wires, and Fig. 6 an enlarged'sectional view on the line y y of Fig. 3.

In said drawings, a and a are wires leading from the operating mechanism of the semaphore and connected with the wires a and a of the operating-tower through intermediate chains a, passing over pulleys a all as clearly shown and of the usual and well-known construction. The pulleys a are loosely mounted on a shaft a having its bearings in'a box h, consisting of the cyclindrical casing h and of the lid or cover 72/ provided with an annular ring or flange h, adapted to engage-the wall h of the said cylindricalcasing h. The said cover is securely connected with the said cylindrical casing by a series of bolts h or in any desired manner, and is preferably provided with a packing-ring h so as to render the same substantially air and water tight.

The bottom h and the cover h are provided with the centrally-arranged inwardly-projecting blocks h and k respectively, which latter form the bearings for the shaft 64 while the wall h of said box is provided with inlet and outlet openings 9 g and i 2", respectively.

Within each of the inlet-openings g gis secured in any desired manner a pipe f, carrying at its free end a pipe (Z of smaller diameter and connected with the pipe f by a reducing-coupling e. Loosely arranged on said pipe d is apipe c, acting as a cover and protector for the pipe d, and is provided at its upper portion with a cap I). Said cap is penetrated by the screw-threaded end b of a hook 17 which screw-threaded end engages a ring I) and is held in position by means of a nut 6 all as clearly shown in Figs. 3 and 5 of the drawings. The wirea is secured to said ring I), while a wire a connects the hook b with the chain (t passing over the pulley a, as above described. It must be remarked that the wired? extends through thepiped into the pipe f, where it is connected with the said chain. I

WVithin each of the outlet-openings i i is secured a pipe 01, connected to a box m, the elongated slot m of which is covered by a lid m secured thereto by bolts m g or in any de: sired manner. To the other end of said box on is secured the leader or pipe 0, preferably laid under ground and extending to within a short distance of the operating-tower. At

the end of said leader or pipe 0 is arranged a T-coupling p, having its central opening provided with a removable plug 1) and its other end connected to a short pipe q, having a cap q. The wire a leading from the operating-tower, penetrates the said cap q and extends through the T-coupling pipe or leader 0 and box m into the pipe n, where it is connected with the other end of the chain a".

The entire system of tubes and boxes as above described is filled with oil, glycerin, or any other suitable lubricant or anticorrosive fluid.

The box on is provided with a removable cover m so that repairs can be made 011 the wire a should occasion occur, while the T- coupling 1) is provided with a removable plug 1) for the purpose of allowing the airto escape, while the system of pipes, boxes, &c., is being filled with the oil, glycerin, &c.

There is no necessity to close the pipe (I, as the pipe 0, which extends over said pipe (I, protects the inlet to the same and prevents water, snow, mud, &c., from entering the said system.

From the foregoing it can be seen that my improved protective means render systems of the character above referred to-such as semaphores, switches, gates, &c.more durable, besides as the oil acts as a lubricant the frietion within said system is greatly reduced.

It will be manifest that the grooved pulleys a, chains a, and their connecting-wires may be replaced by angle-levers in connection with rods or smaller pipes, and that the same protective means can be employed in such modified constructions.

I do not intend to limit myself to the precise construction shown and described, as various alterations can be made without changing the scope of my invention.

Having thus described my said invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination wit h wires,rods and the like, in systems of the character above described, of pipes inelosing said wires, rods, &c., and of a lubricant, such as oil, in said pipes, substantially as and for the purposes described.

2. The combination with wires,rods and the like, in systems of the character above described, of pipes surrounding said wires, rods, &c., a box intermediately arranged between said pipes and also inelosing its respective wire, a lid removably arranged on said box, a lubricant, such as oil, in said pipes and box, all said parts substantially as and for the purposes described.

3. The combination with wires, rods, chains and pulleys in systems of the character above described, of pipes inelosing said rods, wires, chains, &c., a substantially air-tight box or receptacle, inelosing said pulleys, and intermediately arranged between said pipes and connected therewith, a lubricant, such as oil, in said pipes and box or receptacle, all said parts substantially as and for the purposes described.

4. The combination with wires,rods,and the like, and with chains and pulleys, in systems of the character above described, of pipes connecting said wires, rods, chains, &c., a receptacle intermediately arranged between said pipes and connected therewith and inclosing the said pulleys, a box also inserted between said pipes and connected therewith and provided with a removable lid, a lubricant, such as oil, in said pipes, receptacle and box, all said parts substantially as and for the purposes described.

5. The combination with wires,rods and the like, in systems of the character above described, of pipes surrounding and inelosing said wires, rods, &c., a T-coupling at or near one end of said pipes and provided with a removable plug, a loose cap or cover on the other end of said pipes, a lubricant, such as oil, in said pipes and T-coupling, all said parts substantially as and for the purposes described.

G. The combination with grooved pulleys and chains passing over. the same, in systems of the character above described, of a box or receptacle inelosing said pulleys, and provided with inlets and outlets, and a lubricant, such as oil, in said box or receptacle, substantially as and for the purposes described.

7. The combination with wires,rods and the like, in systems of the character above described, of pipes inelosing said wires, rods, &c., a lubricant, such as oil in said pipes, and a closed pipe loosely arranged on and adapted to protect the free ends of the pipes, substantially as and for the purposes described.

In testimony that I claim the foregoingI have hereunto set my hand this 23d day of March, 1897.

JOHN WRIGLEY.
